The decider turned into a thrilling contest as the duo engaged in some good rallies to move neck and neck till 9-9, after Sindhu blew a 4-1 lead.
A net error meant Pai took a slender two-point lead at the interval.
However, things changed thereafter with Sindhu's game crumbling once again as she kept hitting wide and long, allowing Pai to extend the lead to 18-12.
